Choropleth map
✓ Published0🌍 Public
This choropleth map visualizes COVID-19 cases, deaths, and recent 14-day case counts by country, using color to encode case numbers and hover tooltips to reveal detailed statistics. The map uses `d3.geoNaturalEarth1` projection with `d3.geoPath` to render world geography, while `d3.scaleOrdinal` with `schemeSpectral` assigns colors to case values. Data is loaded from a TSV file and TopoJSON world atlas, processed with `topojson.feature`, and rendered as SVG paths. A custom color legend and `d3.zoom` are also implemented.
